Plum Good Health Benefits

Researchers from Texas A&M University and the University of North Carolina have shown a diet containing dried plums can positively affect microbiota, also referred to as gut bacteria, throughout the colon, helping reduce the risk of colon cancer.

The research was funded by the California Dried Plum Board and presented at the 2015 Experimental Biology conference in Boston.

“Through our research, we were able to show that dried plums promote retention of beneficial bacteria throughout the colon, and by doing so they may reduce the risk of colon cancer,” said Dr. Nancy Turner, Texas A&M AgriLife Research professor in the nutrition and food science department of Texas A&M University, College Station.

According to the American Cancer Society, colon cancer is the third leading cause of cancer-related deaths in the U.S. when men and women are considered separately, and the second-leading cause when the figures are combined. During 2015, colon cancer is expected to cause about 49,700 deaths nationwide.

A good amount of research has already shown that one’s diet can alter the metabolism and composition of colon microbiota, which has major implications for disease prevention and treatment, Turner said.

She said there are trillions of bacteria in the intestinal tract and so far more than 400 individual species have been identified. Previous research has shown that disruptions to the microbiota are involved in the initiation of intestinal inflammation and recurrence of inflammatory bouts that can promote development of colon cancer.

“Our research explored the potential cancer-protective properties of dried plums using a well-established rat model of colon cancer,” she said. “Dried plums contain phenolic compounds, which have multiple effects on our health, including their ability to serve as antioxidants that can neutralize the oxidant effect of free radicals that can damage our DNA.”
